Hi, Basically I am a new guy getting familiar with Jboss. This is the exception I have received on my JBoss-4.0.5. java.io.IOException: No properties file: users.properties or defaults: defaultUsers.properties found at org.jboss.security.auth.spi.Util.loadProperties(Util.java:315) at org.jboss.security.auth.spi.UsersRolesLoginModule.loadUsers(UsersRolesLoginModule.java:186) at org.jboss.security.auth.spi.UsersRolesLoginModule.createUsers(UsersRolesLoginModule.java:200) at org.jboss.security.auth.spi.UsersRolesLoginModule.initialize(UsersRolesLoginModule.java:127) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) I am trying to implement JAAS security with my application on Jboss. I have written a class which extends from HttpServlet and implements LoginModule. My aim is to build a small login/password application. From the JSP i can capture the values using the request scope which is available in my class. I am invoking the login() in the service method of my class. I am not using the NameCallback or PasswordCallback or for that matter any of the Callback classes. My authentication will and is hard coded in the class and the authentication will be based on the values received from the JSP. Any help on this issue will be appreciated.
